Question

Which of the following is the end product of glycolysis?

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Glycolysis
 **Related Topics**: Cellular respiration, metabolism, pyruvate metabolism
 **Prerequisites**: Basic understanding of biochemical pathways.
## SOLUTION PATHWAY
**Given Information**:
  The question asks for the end product of glycolysis.
**Method & Steps**:
 1. Understanding Glycolysis:
  Reasoning: Glycolysis is the metabolic pathway that converts glucose into pyruvate.
  Formula/Rule:  Glucose $\xrightarrow{	ext{Glycolysis}}$ 2 Pyruvate + 2 ATP + 2 NADH
 2. Analyzing the options:
  Working: Option A (Glucose) is the starting material, not the end product. Option B (Acetyl CoA) is a product of pyruvate oxidation, a step *after* glycolysis. Option D (Lactate) is a product of fermentation, an anaerobic pathway that occurs *after* glycolysis under oxygen-deficient conditions. Option C (Pyruvate) is the primary end product of glycolysis under aerobic conditions.
 3. Final step:
  Result: Pyruvate is the end product of glycolysis under aerobic conditions.
  Verification: The given reaction shows that pyruvate is formed from glucose during glycolysis.
 ## OPTION ANALYSIS
A :x: Glucose is the substrate (starting material) for glycolysis, not the end product.
B :x: Acetyl CoA is formed after pyruvate is converted in the pyruvate dehydrogenase complex, a step that follows glycolysis.
C ✓: Pyruvate is the main end product of glycolysis.  Under anaerobic conditions, it is further converted to lactate or ethanol.
D :x: Lactate is a product of fermentation, a process that occurs when oxygen is scarce. While pyruvate is often converted to lactate,  pyruvate itself is the primary end product of glycolysis.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing glycolysis with other metabolic pathways (like the Krebs cycle or fermentation):  Remember that glycolysis is the initial breakdown of glucose into pyruvate.
  2.Choosing lactate as the end product: Lactate is a byproduct of anaerobic glycolysis, not the primary end product of the pathway itself.
 **Quick Tips**:
  1.Memorize the overall equation for glycolysis to quickly identify the end product.
  2.Understand that the fate of pyruvate depends on the presence or absence of oxygen.
